Step 1—Verifying the workstation processor Before installing a second Xeon processor chip, verify the number and type of processor chip or cores (based on your operating system) currently installed on your workstation. Record this information for later reference. Windows Vista Business reports the number of physical processor chips installed in the workstation. Microsoft Windows XP Professional and Red Hat Linux report the total number of processor cores contained within the fabric of the processor chip, not just the number of physical processor chips that are installed, and displays the data for either two or four processor cores (depending on your workstation...

Step 2—Preparing for component installation CAUTION: Failure to install the latest system BIOS might cause the workstation to fail when the new processor is installed. NOTE: Workstation models vary. All illustrations are examples only. Download and install updates Check for available system BIOS updates specified for your HP workstation model and operating system at http://www.hp.com/go/workstationsupport.

Step 3—Installing the second processor CAUTION: Observe the following cautions when removing or replacing a processor: — Installing a processor incorrectly can damage the system board.

To install the processor: Remove the plastic cover from the processor. Align the notches in the processor base with the tabs on the socket. Seat the processor into the socket. Ensure that the processor is level with the socket. Figure 2 Installing the processor Close the processor cover plate.

Installing the second processor in HP xw series Workstations After preparing the workstation for component installation, perform the following steps to install the processor: Remove the processor socket protective cover. Figure 3 Removing the socket protective cover If there is a plastic plug in the second processor heatsink hole, remove it. Raise the processor socket handle fully .

Seat the processor into the socket. Ensure that the processor is level with the socket. Figure 5 Installing the processor Close the processor cover plate. Lightly press down on the processor cover plate while closing the socket lever. CAUTION: After installing the processor in the socket, do not power up the workstation without the heatsink attached.

Step 4—Installing the processor heatsink CAUTION: If the heatsink must be removed for any reason after the system has been powered up, the thermal interface must be cleaned off with alcohol and replaced with a new thermal interface. Failure to do so will overheat the processor. CAUTION: After installing the processor in the socket, do not power up the workstation without the heatsink attached.

Fully tighten the remaining pair Tighten all screws to 6 inch-lbs of torque. Figure 7 Tightening the heatsink screws Installing the processor heatsink in the HP xw Workstation series CAUTION: Ensure that the second heatsink does not crush the electrical wires of the first heatsink fan.

To install the heatsink: Align the heatsink mounting posts with their respective threaded mounting holes on the system board . The fan must face toward the front of the workstation. The fins on the fan face toward the rear of the chassis. Connect the heatsink electrical receptacle to the second processor heatsink fan header connector on the system board Figure 8...

To tighten the screws: Partially tighten the four heatsink screws so that the heatsink body remains level. Fully tighten one pair of diagonally opposite screws Fully tighten the remaining pair Tighten all screws to 6 inch-lb of torque. Figure 10 Tightening the heatsink screws Step 5—Reassembling the workstation To reassemble the workstation after installation:...
